What it does
Founder Skills from lool ventures gives founders six skills with a strict workflow and scripts. Market Sizing computes TAM, SAM and SOM top down, bottom up or both, validates claims against external sources and stress-tests assumptions. Deck Review examines a pitch deck, Financial Model Review assesses a financial model and IC Simulation models an investment committee discussion. Competitive Positioning researches competitors and positioning, and Cap-Table models capitalization. The plugin targets Claude Cowork and also works in Claude Code. A skill activates when you ask for that analysis and give it material: a deck, a model or a business description. A general fundraising question does not trigger a full analysis, by design.
Who it is for. Startup founders preparing a round who want to test decks, models and numbers through an investor lens.
Good fit when
- Before a fund meeting the pitch deck is checked for weak spots.
- Market size is estimated and the numbers are backed by sources.
- A startup financial model is reviewed for inconsistencies.
- The ownership structure is modeled ahead of the next round.
Not a fit when
- You want general fundraising advice without documents.
- Data cannot be sent through a search service.
- You need a legal review of deal terms.
Example request
Use the market sizing skill: estimate TAM, SAM and SOM for our B2B service and show sources for the numbers.Limitations
Claude Cowork already has everything needed, while in Claude Code the skill scripts run on your computer, so Python 3.10 or newer is required. Reading Excel models and PDFs may need the `openpyxl` and `pdfplumber` packages. Three skills search the web: market sizing, IC simulation and competitive positioning, so queries derived from your materials go through Claude to a search provider. Deck review, financial model review and cap table do not use the network. Do not load unannounced deal details if that is undesirable.
How to disable. Remove the plugin through `/plugin` in Claude Code or from the plugin card under Customize in Claude Cowork, then the `lool-ventures/founder-skills` marketplace.
FAQ
How do I install Founder Skills in Claude Code?
With `claude plugin marketplace add lool-ventures/founder-skills` and `claude plugin install founder-skills@lool-founder-skills`.
Which six skills are included?
Market Sizing, Deck Review, IC Simulation, Financial Model Review, Competitive Positioning and Cap-Table.
How do I invoke a skill?
With a slash command such as `/financial-model-review` or by saying "Use the financial-model-review skill on our model". If you only describe the task, the assistant may answer from general knowledge.
Is data sent to lool ventures?
No. Documents stay in your Claude session and nothing is sent to lool ventures. Only the three skills with web search use the network.
Do I need anything for PDFs?
`pdfplumber` is advisable for PDFs, and `tesseract` with `pdftoppm` can be added for image slides. Without them the review works as before.
